Printing apparatus and storage medium

A printing apparatus comprising:

• a print head configured to include a plurality of printing element substrates that are capable of ejecting ink from ejection ports by driving printing elements and are arranged into an array extending in a first direction, and configured to perform printing by ejecting ink from the ejection ports onto a print medium, which performs relative movement in a second direction which intersects with the first direction;
• an update unit configured to update target temperatures for temperature adjustment;
• and
• a temperature adjustment unit configured to be capable of executing temperature adjustment for each of the printing element substrates in accordance with the target temperatures,
• wherein the plurality of printing element substrates is arranged so as to extend in the first direction such that adjacent printing element substrates partially overlap in the second direction, and
• wherein, in a case where a difference between the target temperature corresponding to a first printing element substrate located on the downstream side in the second direction among the printing element substrates overlapping in the second direction and the target temperature corresponding to a second printing element substrate located on the upstream side in the second direction is a first value, the update unit updates the target temperature corresponding to the first printing element substrate to a second value, and, in a case where the difference is a third value that is greater than the first value, the update unit updates the target temperature corresponding to the first printing element substrate to a fourth value that is greater than the second value.

A non-transitory computer readable storage medium storing a program for causing a computer to perform a control method of a printing apparatus,

• the printing apparatus comprising:
• a printing element substrate configured to eject ink from ejection ports by driving printing elements onto a print medium that performs relative movement;
• and
• a temperature adjustment unit configured to be capable of executing temperature adjustment for a plurality of areas in the printing element substrate in accordance with target temperatures,
• wherein the plurality of areas includes a first area and a second area that partially overlaps with the first area in a first direction, which is the direction of the relative movement, and that is located on the upstream side relative to the first area,
• the control method comprising:
• a first step for updating the target temperatures corresponding to the plurality of areas based on the target temperature corresponding to the printing element substrate and offset temperatures that are set for the plurality of areas,
• wherein the offset temperatures for the first area and the second area are set so as to make a temperature of the first area become close to a temperature of the second area.
